Abstract

The present invention relates to an apparatus for detecting an object in a blind spot while driving, and in the case of a conventional vehicle, the rearview mirror and the side mirror have a blind spot that cannot detect a detection area to be actually detected. There was an uncomfortable problem of checking the rear and rear, the present invention is to install the infrared sensor 10 in the rear of the rear door of the vehicle to detect a certain distance at 45 ° angle, the detection time is whether the driver's seat When the sensor and the position sensor (30) signal of the shift lever and the engine RPM signal (50) and the direction indicator are satisfied, the blind spot is detected and, according to the detected signal, it is a warning light and a warning buzzer of the instrument panel. It is a warning to prevent driver's momentary mistake.

Description

Object detection device in blind area while driving

The present invention relates to an object detecting apparatus in a blind spot while driving, and more specifically, an infrared sensor for detecting an object at a predetermined distance at a 45 ° angle behind a rear rear door of a vehicle, and a detecting sensor for detecting whether a driver is on a ride. The infrared sensor operates according to the operation signal of the shift lever position sensor, the direction indicator, and the engine RPM signal, and displays and alerts the driver's seat according to the object in the blind spot detected. The present invention relates to a blind spot detection device.

In general, a vehicle uses a side mirror and a rearview mirror to detect an approaching object behind the driving direction while driving, and considers an approaching object reflected by the rearview mirror and the side mirror.

However, the rearview mirror and the side mirror do not reflect the area to be detected when the vehicle is turned left, but reflects immediately after the vehicle, so that the vehicle approaches the rear and rear of the vehicle when entering a large road such as a highway. The vehicle cannot detect the vehicle in the approaching lane, and when the right turn of the intersection does not detect the vehicle approaching from the rear and rear of the access lane, the driver turns his head while driving and detects the state of the rear and rear. Will enter.

That is, in the case of a conventional vehicle, since the rearview mirror and the side mirror have a blind spot that cannot detect a detection area to be actually detected, there is an inconvenience in that the driver turns his head and checks the side rear when the vehicle turns left and enters a big road.

Therefore, the present invention has been made in order to solve the above problems, the left rear door of the vehicle is an infrared sensor that operates in accordance with the operating state of the driver's riding position and the shift lever position and direction lights and the engine RPM signal An object of the present invention is to provide an apparatus and a method installed at a rear side to detect an object within a certain distance at a 45 ° angle, and display and alarm the object to prevent an instant mistake of a driver.

Therefore, the present invention for realizing the above object is to install an infrared sensor at the rear of the vehicle rear door to detect a certain distance at 45 ° angle, the detection timing and the sensor and shift lever to detect whether the driver's seats When the position signal of the engine and the operating state of the RPM signal and the direction indicator of the engine are satisfied, the blind spot is detected, and according to the detected signal, it is installed / configured to warn it as a warning lamp and a warning buzzer of the instrument panel. .

When described in detail with reference to the drawings illustrated for the configuration of the present invention.

An infrared sensor 10 for detecting an approaching object in a blind spot is installed at the rear of the rear door of the vehicle as illustrated in FIG. 1, so that the infrared sensor 10 is detected by several sensors for determining a driving state of the vehicle. Let the timing be determined.

That is, by installing the driver's seat detection sensor 20 to detect the driver's boarding in the lower part of the driver's seat to be turned on when a certain weight (eg 40kg) is detected, the shift lever is selected to the driving stage The shift lever position sensor 30 is installed to detect a case, and the engine RPM signal 50 is discriminated to determine the rotation and the running speed of the engine, and the signal of the direction indicator light to determine whether the direction indicator light is activated. If the above conditions are all satisfied, the infrared sensor 10 may detect the blind spot 40.

In addition, when the infrared sensor 10 detects an object in a blind area while the infrared sensor 10 is operated, a detection signal is output to a warning light and a warning buzzer on the board to alert the driver.

Actions and effects on the configuration of the present invention described above are as follows.

The infrared sensor 10 installed behind the rear door of the vehicle has a driver's seat detection sensor 20 turned on, the shift lever position sensor 30 senses a driving stage, and the RPM signal 50 of the engine is a fixed value. As described above, when all the cases in which the signal 40 of the direction indicator is operated are satisfied, the blind spot is detected.

In addition, when the infrared sensor 10 detects an object from the detection zone, the infrared sensor 10 applies a signal to a warning light and a warning buzzer of the driver's seat panel to display and warn the driver, thereby preventing a driver's instantaneous mistake.

In addition, the method of the present invention, the infrared sensor 10 is installed behind the rear door to detect the object in the blind spot, and the lift sensor 20 and the shift of the driver's seat installed to operate the infrared sensor 10. Signals of the shift lever position sensor 30 for determining whether the lever is selected at the driving stage, an engine RPM signal 50 for dividing the rotation state of the engine, and a direction indicator for discriminating whether the direction indicator is activated. Determining the signal 40 sequentially and operating the infrared sensor 10 when both signals of the sensor are satisfied, and when the infrared sensor 10 detects an object in a blind area, the driver's seat instrument panel The warning lamp and the buzzer of the warning step will be included.

As such, the device of the present invention prevents the driver's instantaneous mistake by detecting and alerting an object in a blind spot when the infrared sensor installed behind the rear door turns left.
